Embodiment Construction

[0042] Hereinafter, we will explain the embodiments of the present invention with reference to the figures.

[0043] The first embodiment is as figure 1 Shown. figure 1 It is an example in which the data center targeted in the present invention is connected via the Internet 110 to general consumers c0 and c1 who access the homepages of corporate user A (AA0), corporate user B (BB0), A company and B company. Here, the clients a0, a1, and a2 have the private network addresses (PNA) of the A company system, and are connected to the gateway D0 in the data center through the gateways A0 and A1 and the virtual private network (VPN). In addition, in the third embodiment, requests from customers c0 and c1 are described.

[0044] figure 2 It shows the structure of the data center DD0. figure 2 It means that in this example, for the Web server group that the user requests to provide a Web (World Wide Web) browser interface, the AP (application) server group that makes the application t...

Abstract

A data center allocates computer resources independently to each user company, and automatically changes a computer allocation in real time in accordance with each load. A control program (P20) forms a computer allocation control table (T22, T23) for each service level contract made between the data center and each user company, and sets the table to a load allocating apparatus (d100). A table (T19) is formed which is used for searching a user company identifier from an IP address (A0) in a user request packet. The load allocating apparatus (d100) checks a service level contract from the user request packet and transfers the user request packet to a proper computer group. The control program (P20) compares the service level contract (T20) with the monitoring result of the operation state of computers, and if the contract condition is not satisfied, the number of allocated computers is changed.

Description

Technical field [0001] The present invention relates to a mechanism and method for allocating resources in a computer system to each user. In particular, it relates to a system composed of multiple computers coupled with each other through a network. When processing multiple user requests, in order to maintain a predetermined service level among users, necessary computing resources are provided to it in real time A resource allocation device and method that can maintain confidentiality among users. Background technique [0002] In order to reduce the cost of the information department, business forms that outsource the operation of the company's information system and the management of the company's homepage to ASP (application·service·provider, application·service·provider) companies are increasing. ASP companies further outsource the supply and management of computer resources to data center companies. [0003] Data center operators cut their own operating costs by preparing ma...
